Archived projects and storage limits

Archived projects and storage limits

Been testing zoho and haven't been able to find an answer to a couple of vital questions. Each of our projects requires numerous large files (we could easily use the 30GB of space on 4 or 5 active projects), and we would require access to many of our archived projects long after they are completed. So,

1. Is there any limitation on the number or age of archived projects?
2. If archived projects count against storage total, is there a way to strip attachments from feed to recover that space without deleting the project?

Does anyone else have this issue and found a solution to make zoho work or them?

Thanks.
